The CUDA LATCH Binary Descriptor: Because Sometimes Faster Means Better Christopher Parker 1 , Matthew Daiter 2 , Kareem Omar 3 , Gil Levi 4 and Tal Hassner 5,6 1 University of Oslo, Norway 2 Nomoko AG 3 University of Alabama in Huntsville, AL, USA 4 Tel Aviv University, Israel 5 Information Sciences Institute, USC, CA, USA 6 The Open University of Israel, Israel Abstract. Accuracy, descriptor size, and the time required for extrac- tion and matching are all important factors when selecting local image descriptors. To optimize over all these requirements, this paper presents a CUDA port for the recent Learned Arrangement of Three Patches (LATCH) binary descriptors to the GPU platform. The design of LATCH makes it well suited for GPU processing. Owing to its small size and bi- nary nature, the GPU can further be used to efficiently match LATCH features. Taken together, this leads to breakneck descriptor extraction and matching speeds. We evaluate the trade off between these speeds and the quality of results in a feature matching intensive application. To this end, we use our proposed CUDA LATCH (CLATCH) to recover structure from motion (SfM), comparing 3D reconstructions and speed using different representations. Our results show that CLATCH provides high quality 3D reconstructions at fractions of the time required by other representations, with little, if any, loss of reconstruction quality. 1 Introduction Quantity has a quality all its own Thomas A. Callaghan Jr. Local features and their descriptors play pivotal roles in many computer vision systems. As such, research on improving these methods has been immense. Over the years, this effort yielded progressively more accurate representations. These improvements were often demonstrated on standard benchmarks designed to measure the accuracy of descriptor matching in the presence of various image transformations and other confounding factors. It remains unclear, however, if the improved accuracy reported on these benchmarks reflects better, more useful representations when used in real world computer vision systems. Take, for example, recent attempts to use deep learning for image feature rep- resentation (e.g., [10,26,40]). There is no question that given sufficient training arXiv:1609.03986v2 [cs.CV] 14 Sep 2016

SUBMERGED COMBUSTION VAPORISERS Over the last decade Process Combustion has provided over 50 submerged combustion vaporiser units to the gas industry. These have been single and multiple burner format, for peak shaving and base load duty applications at many of the large UK refineries and other similar gas terminals, refineries and similar sites throughout Europe and the world.
Process Combustion vaporiser design can offer heat transfer efficiencies in the tube bundle of 99% or greater providing highly efficient vaporisation.
All the vaporiser units Process Combustion supply are fully site commissioned to ensure they reach their load requirements and offer total reliability.
Design Our design skills ensure that safety and reliability are at the forefront of our vaporiser technology. The all-metal burner technology has been developed by Process Combustion over many years and we continue to improve the design to achieve lower NOx levels and for cogeneration applications. We have also carried out multiple to single burner conversion work for clients.
Industries & Applications We have supplied vaporiser systems into many industries including oil & gas, petrochemical and nuclear for the following applications:
• LNG • Ethylene,Propane,Butane • Nitrogen • Oxygen
Vaporisers
The performance of the equipment described in this document will vary depending on the particular design and application.
Process Combustion has many years’ experience in the design and supply of a range of vaporisation equipment and systems to convert cryogenic or fully refrigerated gases to their gaseous state.
CONTROL SYSTEMSVaporisers must be controlled by a system that ensures safety and reliability. Process Com-bustion has in-house expertise to design, build, test and commission fully integrated control panels and flow control skid packages.
Variety of Design Options and Applications
The performance of the equipment described in this document will vary depending on the particular design and application.
STATIC & SKID MOUNTED UNITS
Process Combustion vaporisers can be permanent or mobile. Clients may be major gas utilities or engineering companies wishing to test ‘process critical’ equipment destined for offshore applications, before it is shipped.
HIGH THERMAL EFFICIENCY In submerged combustion the fuel and air are introduced into the burner so that the combustion gases pass downwards and along a distribution tube inside the water tank. The combustion gases then pass out of a sparger arrangement and directly contact with the water which then heats the process tube bundle. For temperatures below 50 °C this is a highly efficient method. For low temperature applications, 100 % nett thermal efficiency is common.
Understanding water chemistry and pH control is important with submerged combustion systems as the combustion products are in direct contact with the water bath. Process Combustion have considerable expertise in this area and can design and supply control systems which maintain operability of the system with increased equipment lifetime.
